There are so many factors that determine your eBike’s range: the size of your battery, the level of motor assist you select, and how much weight you are carrying. Going uphill uses more battery than a flat trail.

To help you figure out the most accurate range estimate for your eBike, please try using Bosch’s range finder tool.
